Unresolved External Symbol in C

Question

The Unresolved external symbol error is preventing the compilation of my code. It specifically is mentioning two functions being called in main. The functions are a part of a switch I am trying to create and it is still under construction. If anyone has any suggestions for how I can fix the bug or improve my code please let me know and thank you in advance. FYI- I already searched for similar questions and they are not specific to my problem...

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
//This is a macro intended for use with the emplyName array.
#define SIZE 20 

//This struct has all the varibles that I will be using in my functions
typedef struct person
{
    char* emplyName[5][SIZE];
    float emplyHours[5];
    float emplyRate[5];
    float emplyGross[5];
    float emplyBase[5];
    float emplyOvrt[5];
    float emplyTax[5];
    float emplyNet[5];
    float emplyTotal[5];
}input;

void menu(void);
void employeeInfo(input* emply);
void editEmployees(input* emply);
void print(input* emply);

int main(void)

    struct person *payroll={""};
    int choice = 0;
    menu();
    scanf_s("%c", &choice);
    switch (choice){
    case '1':

        break;

        emply->emplyGross[i] = (((emply->emplyHours[i])*(emply->emplyRate[i])) + emply->emplyOvrt[i]);

Answer 1

You defined editEmployees() and print() local to employeeInfo().

1. This hides them from the the rest of the program.
2. This is not Standard C.
3. If you'd indented your code properly you most probably would have noticed this yourself.

Same for calculations().
